ANTI-FRICTION JOURNAL-lBOX.

SPECIFICATION forming part of Letters Patent No. 409,307, dated August20, 1889.

Application filed November 22, 1888. Serial No. 291,573. (No model.)

To all whom, it may concern.-

. Be it known that I, WILLIAM S. SHARPNECK, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inAnti-Friction J ournal-Boxes, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to an improvement more particularly designed tobe used in connection with the form of journal-box shown in myapplication Serial No. 284,472, filed September 3, 1888, but may be usedwith other styles of journal-boxes.

It consists in the peculiar construction, arrangement, and combinationof parts hereinafter more particularly described, and then definitelypointed out in the claims.

In the accompanying drawings, Figure 1 represents a vertical centrallongitudinal section of my improvement, and Fig. 2 an end view of thesame.

Referring now to the details of the drawings, A represents an axlepreferably .provided with a hardened-steel ring B, but it may be of anysuitable material or construction.

0 is a bar or spider secured to the case of the box, (not shown,)through which passes a bolt D of peculiar form, preferably having anopening for a key, and having at one end a threaded shank d and at theother a large head (1', near which is a reduced portion d". The threadedend is provided with a nut E and jam-nut E, and the headed end isinclosed by a cup F, having an aperture f 0011- siderably larger thanthe reduced portion of the bolt. In the periphery of this cup is aset-screw G, provided with a jam nut g, which secures in the cup ahardened-steel guide or ring II, having an inwardly-turned flange h.Between this ring II and the head (1' of the bolt D is a disk ofhardened steel I, said ring and disk forming a kind of cup, in which areset anti-friction balls, preferably three, as shown by Fig. 2, whichballs receive the end-thrust of the hardened-steel ring B or axle A, andmay therefore be called the end bearing.

I have found great difliculty heretofore in adjusting the bearingconcentric to the center of the axle; but by the present invention thisis effectually overcome, for by loosening the nuts E E and the set-screwG the cup E and ring H can be readily moved and adjusted,'so that bymoving the ring II until it slips over the end of the ring 13 the cup Fis adjusted concentric with the axle, and then by tightening the nuts EE said cup F is securely held in the proper position. The ring II isthen drawn back in the cup by hand and held in place by the set-screw G.

It will thus be seen that the ring 11 can be readily adjusted andsecured perfectly concentric with the axle, and that its adjustment canat any time be readily changed to suit any change that may occur fromwear or other derangement, whereby the end bearing can be always easilyadjusted concentric with the center of the journal.

\Vhat I claim as new is 1. The combination, with a journal, of a rollingend bearing therefor, a cup having a lateral adjustment transversely ofthe journal, and a movable guide or ring held by said cup and receivingsaid rolling end bearing, substantially as described.

2. The combination, with a journal, of a cup havinga lateral adjustmenttransversely of the journal, a movable guide or ring held by said cup,and a ball held in the guide, substantially as described.

3. The combination, with a journal, of a cup having a lateral adjustmenttransversely of the journal, a movable guide or ring and disk held insaid cup, and means, as the bolt D and nut E, for adjusting said cup,substantially as described.

In testimony whereof I affiX my signature, in presence of two witnesses,this 20th day of November, 1888.

WVILLIAM S. SHARPNEOK.
